Retrofit Solutions for Legacy Track Fastener Upgrades

Modernizing aging tracks without full replacement cuts costs by 40-60%.

Common Retrofit Scenarios:

Wood-to-Concrete Sleeper Transition:

Adapter plates (e.g., Pandrol AD-300) allow new fasteners on old timber ties.

Clip Standardization:

Replace jointed track's dog spikes with elastic clips (improves fatigue life 8x).

Key Products:

Vossloh SH-100: Bolt-on clip retrofit for 1950s-era tracks.

Getzner SRS-2: Sliding plates accommodate legacy rail profiles.

Implementation Challenges:

Gauge adjustments often required (±2mm tolerance).

Nighttime work windows limit productivity.
